Answer:
600
Step-by-step explanation:
if SP>CP,
It is profit [SP - CP = Profit]
if CP>SP,
It is loss [CP - SP = Loss]
Here in the question CP>SP so,
loss = CP - SP
=2500 - 1900
= 600
130 i think let me know if this is right
4+3(7+4 x 2)-100
4+3(7+8)-100
4+3(15)-100
4+45-100=
-51
20x^2+50 = -40x^2+110x [ Taking x as the unknown positive integer ]
